The RE-440 is designed to interface low level control signals to starters and contractors. The Relay will accept 24 VAC or 24 VDC universal input. In this way, the same Relay can be used for either input voltage

The PS-200 accepts either 115, 230 or 24 VAC input and provides fully regulated, short circuit and thermal overload protected 5.0 to 25.0 VDC output. The PS-200 incorporates an inline fuse and terminal strip for the primary line voltage.

The TR-201 is designed to provide reliable and stable VAC power within specification for all Mamac transducers. The TR-201 is available in more than seven different VA ratings to cover all power requirements.

The Mamac A-520 Static Pressure Probe is designed to pick up static pressure in a duct, plenum, air handler or other HVAC equipment. The probe has two orifices vertically opposite each other to cancel out any air flow induced errors.

The A-500 Thermowell is machined from a single piece of brass or stainless steel to provide a rugged and leak proof well for Mamac temperature sensors. Each A-500 Thermowell is precisely machined to 0.255" bore to provide a tight fit for our standard 1/4" O.D. probe. This feature also significantly enhances the thermal transfer from the media to the temperature sensor.
